Abstract Scope |
The printed electronics are currently manufactured by ink-based printing technologies such as inkjet and aerosol jet printers. These ink-based technologies suffer from significant drawbacks, including complex supply chain, extensive time and cost of ink formulation processes, surfactants/contaminants, limited printing inks, machine maintenance/cleaning, and the need for high-temperature post-processing to sinter the particles and remove the surfactants. This talk presents a new laser ablation and sintering-enabled (LASED) dry printing technology where pure nanoparticles of various materials, including metals, semiconductors, and insulators, are laser-generated and laser-sintered in situ and on demand. This eliminates ink-associated manufacturing pollution, contaminations, cost and time, as well as the need for post-processing. It further allows the printing of multimaterial and hybrid structures. This technology transitions electronics printing to a new realm where pure, multimaterial, multifunctional, and hybrid materials are printed on demand for applications ranging from electronics, energy, and healthcare to automotive, aerospace, and defense industries. |
